SEP'ARABLE BUTTON.

SPECIFICATION formingpart of Letters Patent No. 527,555, dated October16, 1894.

Application filed February 16, 1893. Serial No. 462,624- (No model.)

To all whom it may concern.-

Be it known that 1, JOHN HOLMES, a citizen of the United States,residing at Newark,,in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Buttons; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying'drawings, and to letters of reference marked th e on, whichform a part of this specification.

This invention relates to that class of buttons, known as bachelorsbuttons, having, at one end of its shank, a permanent head and, at theother, a removable fastener.

It also relates to that class of buttons in which the outer headcomprises'two plates joined at the peripheries, the rear plate beingmade more concavo-convex, as shown in Figure 3, of the drawingshereinafter referred to, than the front plate, so as to give greaterbody to the button, and render the same more strong to resist the forcesbrought to bear thereon.

The objects of the invention are to reduce the cost of construction andto secure a stronger, less expensive and more sightly article and tosecure other advantages and results some of which will be hereinaftermore fully referred to. k

The invention consists in the improved button and in the combinationsand arrangements of parts, all substantially as will be hereinafter setforth and finally embodied in the clauses of the claim.

Referring to the accompanying drawings in which like letters indicatecorresponding parts in each of the figures, Figs. 1 and 2 arerespectively a side elevation and bottom plan' of the button completeand Fig. 3 is a central longitudinal section of the same with thedetachable fastener removed from the shank thereof. Fig. 4 is a detailsection of the shank stud. Figs. 5 and 6 are detail plans of certainblanks which when bent around the shank serve to hold the same withinthe head of the button, and Fig. 7 is a plan of a fastener adapted tohold the button upon the garment.

In said drawings, (it indicates the head of made of thin sheet metal.

the button, b the shank thereof, and c, the removable fastener adaptedto be held in a peripheral groove at the end of the shank so as tofasten and hold the button to the garment in any manner common to theclass known as bachelors buttons, to which the invention particularlyrelates.

The head of the button, a, consisting of the outer plate, a, and innerplate or collet, a is preferably formed up from sheet metal in anymanner usual in the art. Said plates are of different degrees ofconcavo-convexity, or are so formed that they engage at their edges andat their central parts form, therebetween, a chamber, in which theshank-fastening means are arranged. as above, when joined, give body tothe head of the button and add strength thereto so that the buttonis noteasily bent even though The means for The two plates formed fasteningthe head to the shank,-also, are

concealed by the front plate. Said front and rear, or inner and outerplates are held together, preferably, by turning the peripheral edge ofthe outer plate over that of the inner plate in the manner indicated inthe sectional figure.

The present invention relates more particularly to the manner offastening the shank to the head.

The shank consists of a short section of wire which extends through theperforated inner plate and extends into engagement with the inner sideof the front or outer plate, a, which latter is pressed up at the centerso as to form a recess or socket, a to receive the end of the said wiresection or stud. Said section or stud may be pointed to enter the recessand be centered therein and adjacent to the back or inner plate the sameis notched or peripherally grooved, as at b, to receive a collar, d,which projects laterally from the said stud and serves as a shoulder orbearing for the back plate, the latter engaging said bearing and holdingthe stud groove, pressure was applied and the plate flattened, by whichoperation the perforation was contracted and the plate thus held to theshank. In this construction the amount of contraction was in all caseslimited and varied in accordance with the variations in the quality ofthe metal, and thus, the fastening was not certain and strong towithstand the great strain frequently brought thereon when in service.

The method of forming the collar of my invention and the means employedavoid uncertainty, and always produce a construction having adequatestrength.

The collar herein is shown to be formed of a short section of flat wirebent first into the form of a U, as indicated in Fig. 5, and then placedin the groove or annular notch and again bent so that the ends meet orapproximate one another, the fiat wire thus entering deeply into thegrooves and having a rigid and strong connection with the shank. Theplates, before referred to, being struck from sheet metal, required alarge amount of wastage of the sheet and to secure any materialcontraction of the central perforation were necessarily of considerablediameter and this tended to create considerable waste. By the use offlat wire, all such Waste is avoided and the buttons are not only ofbetter quality but are also of reduced cost because of my improvedconstruction.

At the outer end of the stud, where it is exposed to form the shank andpass through the material of the garment prior to receiving thefastener, the same is notched or grooved as at b to receive theremovable fastener, c, in the ordinary manner.

The construction of the collar maybe modified without departing from theinvention, and in Fig. 6 I have shown such a modification.

Having thus described the invention, what I claim as new is The improvedbachelors button herein described, in which is combined with the innerand outer plates of the head, which are centrally separate to form achamber and are peripherally joined, a shank or stud extend ing throughthe inner plate into engagement With the front plate and having, at apoint between said plates, just within the inner plate, a peripheralgroove, a bent flat wire, adapted to be first bent into a U shape,fitted into the peripheral groove, the ends of which are turned towardone another so as to meet or approximate one another, and thus forming arigid collar inseparable from said stud, the outer edge of which forms ashoulder which engages the inner side of said inner plate, and aseparable fastener, c, all said parts being arranged, combined andadapted to operate, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this4th day of February, 1893.
